  • Contractor was carrying a memory stick containing the personal data of all of the 460,000 residents of Amagasaki, western Japan, during drinks after work
  • The man spent hours drinking in a local restaurant and eventually passed out
  • When he woke up, the man realised he had lost the bag containing the USB

A Japanese city has been left with more than a headache after admitting a contractor lost a USB containing personal data on all 460,000 residents during a night out.

The western city of Amagasaki said Thursday that a private contractor, whose name has not been disclosed, was carrying the memory stick during drinks after work.

The man, who was working on a municipal pandemic relief programme, spent hours drinking in a local restaurant before passing out on the street on Tuesday night, local media reported.

But when he eventually woke up, he realised that he had lost his bag containing the USB.

'We deeply regret that we have profoundly harmed the public's trust in the administration of the city,' an Amagasaki official told a press conference.

The man, said to be in his 40s, had transferred the personal information of the entire city's residents onto the USB on Tuesday before meeting colleagues for a night out.   

It included the names, genders, addresses, birthdays and other personal information of all the city's residents, as well as tax data and bank account information on some locals, the city said.

But there may be a silver lining, as the city says the data was encrypted and the USB locked with a password. So far, officials said, there was no sign the information had been accessed.

The loss has been reported to police, who are investigating.
